The Impacts of Junk Food on Health

presentation about junk food

Energy-dense, nutrient-poor foods, otherwise known as junk foods, have never been more accessible and available. Young people are bombarded with unhealthy junk-food choices daily, and this can lead to life-long dietary habits that are difficult to undo. In this article, we explore the scientific evidence behind both the short-term and long-term impacts of junk food consumption on our health.

Introduction

The world is currently facing an obesity epidemic, which puts people at risk for chronic diseases like heart disease and diabetes. Junk food can contribute to obesity and yet it is becoming a part of our everyday lives because of our fast-paced lifestyles. Life can be jam-packed when you are juggling school, sport, and hanging with friends and family! Junk food companies make food convenient, tasty, and affordable, so it has largely replaced preparing and eating healthy homemade meals. Junk foods include foods like burgers, fried chicken, and pizza from fast-food restaurants, as well as packaged foods like chips, biscuits, and ice-cream, sugar-sweetened beverages like soda, fatty meats like bacon, sugary cereals, and frozen ready meals like lasagne. These are typically highly processed foods , meaning several steps were involved in making the food, with a focus on making them tasty and thus easy to overeat. Unfortunately, junk foods provide lots of calories and energy, but little of the vital nutrients our bodies need to grow and be healthy, like proteins, vitamins, minerals, and fiber. Australian teenagers aged 14–18 years get more than 40% of their daily energy from these types of foods, which is concerning [ 1 ]. Junk foods are also known as discretionary foods , which means they are “not needed to meet nutrient requirements and do not belong to the five food groups” [ 2 ]. According to the dietary guidelines of Australian and many other countries, these five food groups are grains and cereals, vegetables and legumes, fruits, dairy and dairy alternatives, and meat and meat alternatives.

Young people are often the targets of sneaky advertising tactics by junk food companies, which show our heroes and icons promoting junk foods. In Australia, cricket, one of our favorite sports, is sponsored by a big fast-food brand. Elite athletes like cricket players are not fuelling their bodies with fried chicken, burgers, and fries! A study showed that adolescents aged 12–17 years view over 14.4 million food advertisements in a single year on popular websites, with cakes, cookies, and ice cream being the most frequently advertised products [ 3 ]. Another study examining YouTube videos popular amongst children reported that 38% of all ads involved a food or beverage and 56% of those food ads were for junk foods [ 4 ].

What Happens to Our Bodies Shortly After We Eat Junk Foods?

Food is made up of three major nutrients: carbohydrates, proteins, and fats. There are also vitamins and minerals in food that support good health, growth, and development. Getting the proper nutrition is very important during our teenage years. However, when we eat junk foods, we are consuming high amounts of carbohydrates, proteins, and fats, which are quickly absorbed by the body.

Let us take the example of eating a hamburger. A burger typically contains carbohydrates from the bun, proteins and fats from the beef patty, and fats from the cheese and sauce. On average, a burger from a fast-food chain contains 36–40% of your daily energy needs and this does not account for any chips or drinks consumed with it ( Figure 1 ). This is a large amount of food for the body to digest—not good if you are about to hit the cricket pitch!

  • Figure 1 - The nutritional composition of a popular burger from a famous fast-food restaurant, detailing the average quantity per serving and per 100 g.
  • The carbohydrates of a burger are mainly from the bun, while the protein comes from the beef patty. Large amounts of fat come from the cheese and sauce. Based on the Australian dietary guidelines, just one burger can be 36% of the recommended daily energy intake for teenage boys aged 12–15 years and 40% of the recommendations for teenage girls 12–15 years.

A few hours to a few days after eating rich, heavy foods such as a burger, unpleasant symptoms like tiredness, poor sleep, and even hunger can result ( Figure 2 ). Rather than providing an energy boost, junk foods can lead to a lack of energy. For a short time, sugar (a type of carbohydrate) makes people feel energized, happy, and upbeat as it is used by the body for energy. However, refined sugar , which is the type of sugar commonly found in junk foods, leads to a quick drop in blood sugar levels because it is digested quickly by the body. This can lead tiredness and cravings [ 5 ].

  • Figure 2 - The short- and long-term impacts of junk food consumption.
  • In the short-term, junk foods can make you feel tired, bloated, and unable to concentrate. Long-term, junk foods can lead to tooth decay and poor bowel habits. Junk foods can also lead to obesity and associated diseases such as heart disease. When junk foods are regularly consumed over long periods of time, the damages and complications to health are increasingly costly.

Fiber is a good carbohydrate commonly found in vegetables, fruits, barley, legumes, nuts, and seeds—foods from the five food groups. Fiber not only keeps the digestive system healthy, but also slows the stomach’s emptying process, keeping us feeling full for longer. Junk foods tend to lack fiber, so when we eat them, we notice decreasing energy and increasing hunger sooner.

Foods such as walnuts, berries, tuna, and green veggies can boost concentration levels. This is particularly important for young minds who are doing lots of schoolwork. These foods are what most elite athletes are eating! On the other hand, eating junk foods can lead to poor concentration. Eating junk foods can lead to swelling in the part of the brain that has a major role in memory. A study performed in humans showed that eating an unhealthy breakfast high in fat and sugar for 4 days in a row caused disruptions to the learning and memory parts of the brain [ 6 ].

Long-Term Impacts of Junk Foods

If we eat mostly junk foods over many weeks, months, or years, there can be several long-term impacts on health ( Figure 2 ). For example, high saturated fat intake is strongly linked with high levels of bad cholesterol in the blood, which can be a sign of heart disease. Respected research studies found that young people who eat only small amounts of saturated fat have lower total cholesterol levels [ 7 ].

Frequent consumption of junk foods can also increase the risk of diseases such as hypertension and stroke. Hypertension is also known as high blood pressure and a stroke is damage to the brain from reduced blood supply, which prevents the brain from receiving the oxygen and nutrients it needs to survive. Hypertension and stroke can occur because of the high amounts of cholesterol and salt in junk foods.

Furthermore, junk foods can trigger the “happy hormone,” dopamine , to be released in the brain, making us feel good when we eat these foods. This can lead us to wanting more junk food to get that same happy feeling again [ 8 ]. Other long-term effects of eating too much junk food include tooth decay and constipation. Soft drinks, for instance, can cause tooth decay due to high amounts of sugar and acid that can wear down the protective tooth enamel. Junk foods are typically low in fiber too, which has negative consequences for gut health in the long term. Fiber forms the bulk of our poop and without it, it can be hard to poop!

Tips for Being Healthy

One way to figure out whether a food is a junk food is to think about how processed it is. When we think of foods in their whole and original forms, like a fresh tomato, a grain of rice, or milk squeezed from a cow, we can then start to imagine how many steps are involved to transform that whole food into something that is ready-to-eat, tasty, convenient, and has a long shelf life.

For teenagers 13–14 years old, the recommended daily energy intake is 8,200–9,900 kJ/day or 1,960 kcal-2,370 kcal/day for boys and 7,400–8,200 kJ/day or 1,770–1,960 kcal for girls, according to the Australian dietary guidelines. Of course, the more physically active you are, the higher your energy needs. Remember that junk foods are okay to eat occasionally, but they should not make up more than 10% of your daily energy intake. In a day, this may be a simple treat such as a small muffin or a few squares of chocolate. On a weekly basis, this might mean no more than two fast-food meals per week. The remaining 90% of food eaten should be from the five food groups.

In conclusion, we know that junk foods are tasty, affordable, and convenient. This makes it hard to limit the amount of junk food we eat. However, if junk foods become a staple of our diets, there can be negative impacts on our health. We should aim for high-fiber foods such as whole grains, vegetables, and fruits; meals that have moderate amounts of sugar and salt; and calcium-rich and iron-rich foods. Healthy foods help to build strong bodies and brains. Limiting junk food intake can happen on an individual level, based on our food choices, or through government policies and health-promotion strategies. We need governments to stop junk food companies from advertising to young people, and we need their help to replace junk food restaurants with more healthy options. Researchers can focus on education and health promotion around healthy food options and can work with young people to develop solutions. If we all work together, we can help young people across the world to make food choices that will improve their short and long-term health.

Obesity : ↑ A disorder where too much body fat increases the risk of health problems.

Processed Food : ↑ A raw agricultural food that has undergone processes to be washed, ground, cleaned and/or cooked further.

Discretionary Food : ↑ Foods and drinks not necessary to provide the nutrients the body needs but that may add variety to a person’s diet (according to the Australian dietary guidelines).

Refined Sugar : ↑ Sugar that has been processed from raw sources such as sugar cane, sugar beets or corn.

Saturated Fat : ↑ A type of fat commonly eaten from animal sources such as beef, chicken and pork, which typically promotes the production of “bad” cholesterol in the body.

Dopamine : ↑ A hormone that is released when the brain is expecting a reward and is associated with activities that generate pleasure, such as eating or shopping.

Topic summary contributed by volunteer(s): Randy

High calorie, low nutrient junk foods are a major contributing factor to why the Western diet rates so poorly . The intake of junk food should be as low as possible . In the U.S. dietary guidelines , the U.S. government has not directly stated this , likely due to food industry influence . In 2005, the meat, egg, dairy, and junk food industries may have influenced the government in their food recommendation graphic to give less visual importance to whole, plant foods.

Industry influence may also be a factor as the world’s large association of nutritional professionals, the Academy of Nutrition and Dietetics and the American Academy of Family Physicians receive sponsorship dollars from meat, dairy, processed, and junk food companies each year. With the obesity epidemic, a key policy issue is whether food companies should be regulated to sell less junk. In the meantime, most people agree that overall, the public needs to limit its intake of junk food and animal fat , and eat more fruits and vegetables. The American Heart Association recommends the equivalent of a maximum of only two meals per week with meat, dairy, or junk food, with all other meals consisting of unprocessed plant foods. Those eating a Paleo diet agree that junk food intake should be greatly reduced . Avoiding processed junk food is almost universally recommended . Only when foods are ranked by cost per calorie is junk foodcheaper than fruits and vegetables.

When people regularly eat calorie dense animal and junk foods, they may blunt their pleasure centers so much that they overeat to compensate . When children are given the choice to eat as much as they want of raisins, grapes, chips, or cookies, children choose to eat less fruit and more junk food .  Artificial sweeteners , which can be in junk foods, often maintain cravings for sweet foods. Plate and cup color may also affect the amount junk food eaten .

Unlike whole plant foods, junk food has little or no fiber and generally lack the thousands of phytonutrients available in fruits and vegetables. Too much junk food may contribute to excess intake of phosphorus and trans fats , considered harmful to health .

Junk food intake appears to raise the risk for high blood pressure , acne , and obesity . Junk food can raise LDL cholesterol , increase the severity of diabetes , and raise the risk of diseased arteries . Luckily, if we abstain from eating heavily fried and salted foods, our taste buds can change relatively quickly .

Modern society has brought with it many comforts and conveniences, yet when it comes to the United States’ health and nutrition, the advancements haven’t always been positive for your overall health. Doing things better, cheaper and faster may work well for manufacturing microprocessors but it doesn’t work well with the mind, body or spirit. The invention of factory farming, refined and processed pre-packaged food and fast food has come at a high price – your health. You can find your own way to good health by learning the basics of holistic health including what is safe and what is dangerous in modern food. With knowledge comes the empowerment to debunk misnomers from food and nutrition studies born out of conflicts of interest and to see through devious marketing from large food and beverage manufacturers focused only on one thing (and it’s not your health.) Consuming a diet filled with the “food like stuff” that has become a basic of today’s Standard American Diet (SAD), results in excess weight, illness, dis-ease and mental fog from the dangerous components of our food. As an unique individual, biochemically and spiritually, it’s important to find what works best for you. When you know the basics, you can seek out and find what foods, including amounts and combinations, work best for your individual body. It’s vital to experiment to find the right combination of food, exercise and spiritual nurturing so you not only feel great, you are the best, most dazzling version of you. Empowerment through knowledge will allow you to find your own way to a life of vibrant health and a trim, healthy body. Awareness of good nutrition is freedom from fad diets, counting calories and points, reading unhelpful nutritional labels and from confusion over misleading nutritional information in the media. Changing what you know and the way you eat and treat your mind, body and spirit will transform your life.

With the increasing use of the internet and the ease of exchange of multimedia content, the protection of ownership rights has become a significant concern. Watermarking is an efficient means for this purpose. In many applications, real-time watermarking is required, which demands hardware implementation of low complexity and robust algorithm. In this paper, an adaptive watermarking is presented, which uses embedding in different bit-planes to achieve transparency and robustness. Local disorder of pixels is analyzed to control the strength of the watermark. A new low complexity method for disorder analysis is proposed, and its hardware implantation is presented. An embedding method is proposed, which causes lower degradation in the watermarked image. Also, the performance of proposed watermarking architecture is improved by a pipe-line structure and is tested on an FPGA device. Results show that the algorithm produces transparent and robust watermarked images. The synthesis report f...

Why Your Brain Hates Junk Food

Highly processed food alters liver function, making you hungrier and destroying neural resilience..

By Scott C. Anderson published January 2, 2024 - last reviewed on January 2, 2024

Ruta/Adobe Stock

The health of your brain, science is making clear, has a lot to do with the health of your gut, which, of course, has much to do with what you feed it. That raises a whole new set of concerns about junk food and offers yet more evidence that modern diets are failing us. Many highly processed foods are potentially dangerous, in part because they disregard the fate of the billions of bugs that live in the gut and carry out a surprising array of bodily functions. But it is pure folly to ignore these bacteria, especially since they are so crucial to physical and mental health.

How important? A new study from Tufts University contends that better microbe-oriented diets “could avert approximately 1.6 million hospitalizations and result in an estimated net savings of $13.6 billion in health care costs in the first year alone.”

The microbes in your gut differ from those in mine, and they vary daily. The diversity of gut microbes allows for an astonishing number of genes , outnumbering our own genes by a factor of 100. Courtesy of those genes, good bacteria produce nourishing substances that feed and heal the cells lining your gut. If you don’t support those good bacteria, your gut cells may become hungry and disease-prone. Your gut may become leaky enough to allow bacteria and toxins through.

Once bacteria breach the gut lining, the heart pumps them to every organ in the body, including the brain. The upshot: depression , anxiety , paranoia , psychosis , cognitive difficulties, and dementia .

The term processed as applied to food can be confusing. It defines a food that has undergone any change from its natural state. Many processed foods are perfectly fine. Shelled nuts, for instance, are processed to remove an inedible shell. Grains are processed by milling to turn them into flour. Other foods are so highly processed that it’s difficult to identify the source material. Think cheese puffs, Twinkies, vegan burgers.

One of the first steps in processing foods is removal of fiber. After all, fiber is indigestible and makes products brown. Take the fiber out and you have beautiful white foods that are easy to color any way you wish.

But fiber is an important macronutrient, and it is meant especially for your gut microbes, not you. That single alteration—eliminating fiber—may be the worst thing that has happened to the American diet over the last 70 years. As a result, the microbial composition of our guts is changing, and some species are even becoming extinct.

There’s more: Processed foods often contain emulsifiers, which smooth texture, extend shelf life, and keep ingredients mixed. Some, like carboxymethylcellulose and polysorbate 80, can significantly affect intestinal microbes, killing some species, boosting others, but generally destroying diversity, the single best measure of gut health, and promoting gut inflammation, often a precursor to systemic problems.

There are thousands of nutrients in food that are good for you, but they can be classified into four broad categories: fiber, fat, protein, and carbs. Let’s imagine a food called EquiStuff, made with an equal amount of each macronutrient.

Now take out the fiber to improve taste and texture, and you’re left with one-third fat, one-third protein and one-third carbs. If we then take the fat out of EquiStuff, we’ve got a totality of half protein and half carbs.

We didn’t set out to do this, but the carbs in EquiStuff have gone from 25 percent to 50 percent. By taking out two macronutrients, we doubled the carbs. You don’t even need to add carbs like sugar to make something sweeter, although that is done often enough. Remove the fat and fiber and the job is done for you. Sadly, sugar is not good for a balanced gut microbiome .

Fructose and glucose are the main sugars in our diet, but they are processed differently by the body. Glucose is the primary energy source, beloved by brain cells, ushered directly into cells by insulin to provide energy to muscles and other tissues. Fructose, on the other hand, is processed by the liver.

Because fructose is sweeter, easier to use, and cheaper than cane sugar (thanks to government subsidies), food manufacturers add extra amounts to products in the form of high-fructose corn syrup, the most popular version of which has a fructose level of 55 percent, although it can go as high as 90 percent.

A fructose-rich diet can alter the microbiome, leading to gut problems, metabolic disorders, and brain dysfunction. The liver converts excess fructose to fat. In the process, cellular energy levels are miscalibrated by the liver, triggering hunger. It’s an ominous sign when eating doesn’t sate you but makes you hungrier.

Over time, a fructose overload can lead to obesity and liver disease. A continued surplus of fructose may increase the risk of nonalcoholic fatty liver disease and proceed further to nonalcoholic steatohepatitis, two diseases affecting an increasingly large percentage of the population. They are disproportionately affecting children, who are already in the throes of an obesity epidemic. Almost 40 percent of obese children will go on to develop liver disease.

Some studies have found that extra fructose in the diet—even temporarily—can disturb normal nerve growth in the brain. A week of fructose consumption, far less than needed to affect liver function, is sufficient to reduce plasticity of the brain’s hippocampus, a structure particularly vulnerable to nutritional stressors. It also compromises energy production by the mitochondria and weakens defenses against oxidative stress . The effects on neural function may be setting the stage for neurodegenerative diseases.

The liver’s impact on the brain is profound. Depression, anger , and irritability have long been known as fellow travelers with liver disease. Hippocrates knew 2,500 years ago that liver patients exhibited troubled behavior: “Those whose madness arises from [the liver] shout, play tricks, and will not keep still, but are always up to some mischief.” Hippocrates also said, “All disease begins in the gut.”

Bacteria in your gut are significant producers of neurotransmitters, including dopamine and serotonin, among many bioactive substances. The gut-produced agents, which can communicate with your brain via the vagus nerve , are the same neurotransmitters targeted by psychoactive drugs, such as SSRIs . Pumped up by excess sugar, pathogenic bacteria in the microbiome can alter the lining of the gut and lead to leaky gut, opening the door to systemic inflammation. Over time, inflammation can undermine cognition and mood.

For the sake of brain health, cutting back on processed food and replacing it with fiber-filled veggies, like onions, broccoli, artichokes, and beans, is a smart strategy. Good fiber and beneficial bacteria themselves can be found in fermented foods like sauerkraut, kimchee, kefir, and yogurt.

If you can’t flip the dietary script, try probiotic or prebiotic fiber supplements for a concentrated dose of the good stuff. This isn’t an all-or-nothing life change. But every step you take toward increasing fiber in your diet is a step toward rejuvenating your gut bacteria and protecting your brain health.

Junk Food, Junk Brain

  • Junk food reduces both neurogenesis and neuroplasticity.
  • Junk food is designed to ignite tastes that encourage you to demand more of what undermines you.
  • A diet loaded with junk food rapidly and lastingly changes brain receptors that respond to food cues, impeding self-control while motivating you to eat more.
  • High levels of sugar and fat in junk food tilt the brain toward inflammation, notably in the hippocampus, seat of memory .

10 Key Advantages and Disadvantages of Junk Food

presentation about junk food

Junk food’s confusing.

The clue’s in the name right?! It’s junk!

You’d think anything synonymous with trash, rubbish, or garbage wouldn’t be particularly appetising. But we love it.

Indeed, it accounts for almost 30% of the average American’s caloric intake.

To put it another way, 30% of the American diet is junk!

Clearly, there are both advantages and disadvantages of junk food to know about. If there weren’t any positives, then nobody would eat it.

But we do, so there are.

Looking for insight into the pros and cons of junk food? I’ve laid out what seems to be the primary ones in the coming post.

Check them out!

Here are the primary advantages of junk food!

5 Key Advantages of Junk Food

Let’s start with the good stuff. What is it that compels so many of us to eat junk food?

1. It’s Tasty

First off, it tastes good.

Pizzas, burgers, fried chicken, fries, hot dogs, Chinese…you name it, and it tastes bloody good.

It’s all sweet, salty, full of flavour and coated in delicious sauces. As the good old Colonel puts it, junk food’s finger lickin’ good.

Placed alongside a bland green salad and there’s no competition. Most people would go for the junk food every time. You only have to smell the bacon frying, the burgers grilling, and the pizzas cooking for the saliva to start flowing.

It tastes too good to resist.

2. It’s Quick and Easy

Junk food is also incredibly convenient.

People are busy.

They’ve got responsibilities and commitments that take up time. We’re in a hurry, and need to get things done.

Consider lunch breaks.

With 30 minutes away from the job to relax and reboot, nobody wants to spend time preparing a meal. The speed with which junk food comes out makes it appealing.

There’s no effort involved. You get the food in minutes, eat it, and then get back to socialising and enjoying your break.

3. It’s Available 24/7

Likewise, junk food’s always available.

Junk food restaurants are everywhere, around every corner, and are open at all times.

Many of them literally never shut.

That’s good news when you get a bad case of late-night munchies. Or if you’ve stayed late at the office and need a last minute meal to take home. Or if you’re on a tight schedule and can’t go far to find food.

People naturally seek convenient solutions. The path of least resistance is built into our systems. The fact that junk food is as tasty as it is convenient makes it hard to resist.

Two more junk food advantages to come!

4. It’s Cheap

Don’t forget how inexpensive it is either.

This is a big deal.

We live in incredibly difficult financial times. Consumer debt hovers at around $14 trillion . People are operating under masses of financial pressure. Every cent counts.

Making ends meet is a very real issue for many.

And healthy food is more expensive. Buying organic produce and preparing well-rounded nutritious meals sounds ideal. But as long as it costs more money than junk food, which it usually does, there’s less (financial) incentive to eat a healthier diet.

It’s the perfect triad: tasty, convenient, and cheap. For many, that makes junk food the go-to for their meals.

5. It’s a Kids’ Favourite

And kids love it too.

The importance of that shouldn’t be understated!

It’s a big deal for busy parents with fussy children. Nobody wants to spend time, effort and money on meals their kids refuse to eat.

Sometimes you just want the easy route, and junk food is definitely that.

For one thing, you don’t have to cook or do the dishes. Secondly, the kids will eat it without complaining or causing a fuss.

Want to read a similar post? Here are the advantages and disadvantages of fast food .

On to the disadvantages of junk food to think about!

5 Key Disadvantages of Junk Food

Onto the downsides. Here are the cons of junk food that more of us should probably keep in mind.

1. It’s Unhealthy

This is the biggie.

Junk food tends to be far worse for our health than more nutritional options.

A greasy burger covered in cheese and bacon might seem far more appetising than the loose-leaf salad on the menu. But it’s not as good for you.

Junk food has masses of fat, salt, and sugar- not to mention preservatives, additives, and a host of other questionable ingredients. Your physical health suffers when junk food is eaten in excess.

Eat it every once in awhile and you’ve got less to worry about (as long as the rest of your diet is well-balanced and nutritious). Eat it all the time, though, and you can do lasting damage.

Your heart suffers, your cholesterol suffers, your skin suffers, your energy-levels suffer, and so on. You’re more susceptible to serious health issues, such as diabetes, heart disease, and cancer. And more.

Junk food might not be entirely to blame for such challenges. Levels of exercise, underlying health conditions, and so on make a big difference too. It does, however, have a significant role to play.

2. It Contributes to Weight Gain

Obesity is rampant in the US.

Almost 45% of the country is obese. That’s not far off 1 in every 2 people who have it.

It’s scary, and junk food plays its part in that.

Junk food is intensely calorific. It’s also got all the sugar, bad fat and salt I mentioned above. Eat enough of the stuff and you’ll gain weight with greater ease than consuming healthier foodstuffs.

That’s bad news for kids who love junk food, but it ain’t exactly good for adults either.

Obesity is no joke, but being overweight in general isn’t great. Aside from the impact on self-esteem, it also has damaging effects on all aspects of health. Heck, the likelihood of dying shoots up enormously.

Almost 3 million adults die annually from being overweight or obese.

Going easy on the junk food is, arguably, a matter of life and death!

3. It Makes You Feel Sick (In Large Quantities)

Junk food isn’t as filling as more nutritional alternatives.

You have to eat more to feel full. Likewise, the sheer tastiness of it means people often gorge themselves on junk food anyway.

The trouble is that doing so, aside from being very unhealthy, makes you feel sick!

How often have you dug your way to the bottom of the ice-cream tub only to feel awful afterward? It’s hard to stop when something tastes so good! Alas, nothing good comes from it.

Junk food earns its name for a reason. Put rubbish into your body and it’s natural to feel ill as a result.

We’re nearly at the end of these junk food disadvantages. Here are two more:

4. It Impacts Mental Health Too

Physical health is only one part of the problem.

Junk food impacts the mental side of things too.

It does so in a number of ways. First off, there’s a direct link to physical and mental health. If your body feels good, then so does the mind; and vice versa.

Being overweight or obese, or simply feeling sick after overeating, is a recipe for trouble. Your body doesn’t have what it needs; your mind and mood suffer.

Throw in the negative self-image that comes with it and you’re in for a rocky time.

Eat a junk food meal and the sugar, saturated fats, and carbs spike your blood sugar levels. You get a rush of energy that crashes soon after. Your mood drops in the process.

Depression, low mood, anxiety, irritability, and other negative states may occur with increasing frequency.

5. It’s Addictive

Finally, junk food is highly addictive.

All the fat, sugar, salt, and energy-dense ingredients in it are what our brain and body think they want. It’s built into our systems!

Our primal circuitry was built upon uncertainty of resources.

Back in the day, we didn’t know when the next meal would come. You’d have to hunt and gather your food; naturally, there would be times of abundance and times of scarcity.

High-energy, fat-dense foods became valuable. If you got your hands on some, then you’d gorge on them to stock up for rainier, colder, bleaker time with fewer resources.

We still operate under that system, even though we no longer face the same trials.

Most of us have access to sufficient food at all times. But we’ll still get happily knock-back a burger, fries, and thick-shake, because that’s what our brains say we need!

Junk food triggers the pleasure center of the brain. We get a kick when we consume it, which makes us think it’s good. We eat more and more and more and become hooked on the stuff.

It becomes hard to say no to. We begin associating hunger with eating it. Just the thought of junk food gets our mouths watering.

We get addicted.

But we suffer, physically and mentally, in the process.

The Advantages and Disadvantages of Junk Food

Millions of people eat junk food every single day.

It’s the go-to meal choice for many.

And the advantages of junk food make it easy to understand why! It solves a host of ‘problems’ that many of us face.

However, as we’ve seen, there are both advantages and disadvantages of junk food worth knowing about. With the cons in mind, the pros might be harder to justify.

Hopefully, this post will help you make your mind up about whether junk food is the best option (literally) on the table.

WEATHER ALERT

A special weather statement in effect for Central Marion and Western Marion Regions

Ucf trustee among those busted in prostitution sting at seminole parks, 3 men face charges in undercover operation at liberty and sandlando parks.

Anthony Talcott , Digital Journalist

SEMINOLE COUNTY, Fla. – A prostitution sting ended with the arrests of three men — including a Board of Trustees member at the University of Central Florida and an employee with the Seminole County Sheriff’s Office, according to investigators.

In several arrest reports, deputies said they performed an undercover operation at two Seminole County parks on Thursday: Liberty Park in Lake Mary and Sandlando Park in Altamonte Springs.

Recommended Videos

“This operation was about repeated issues regarding people exposing their sexual organs and conducting lewd and indecent acts at the park,” one report reads.

Using the application “Sniffies” — defined as a “map-based hookup web app for gay, bisexual and bicurious men” — undercover agents messaged suspects who agreed to show up to the parks for sexual favors, the reports show.

The suspects arrested during this operation were as follows:

  • Harold Mills, 53 — Arrested at Sandlando Park in Altamonte Springs
  • Jairo Areis, 39 — Arrested at Liberty Park in Lake Mary
  • Leroy Green, 35 — Arrested at Liberty Park in Lake Mary

Mills serves as a board member at UCF, Guidewell, Florida Blue, Rollins College, LIFT Orlando and the Dr. Phillips Performing Arts Center, according to UCF officials .

Deputies said Mills had exposed his genitals to one of the undercover agents when they stood at the open window of his driver door in the park.

After asking for sexual favors, Mills was placed in handcuffs, though he claimed that he “was simply clearing his mind” by visiting the park, the report says.

Areis was also arrested after reportedly showing his genitals to an undercover agent under the pavilion at Liberty Park, deputies added.

Meanwhile, Green — an employee at the SCSO — was caught exposing his genitals and asking an undercover agent to perform sexual favors on him, according to detectives.

Green has since resigned from his position, the sheriff’s office announced.

“We will let the documents speak for themselves,” an SCSO spokesperson told News 6.

Mills faces charges of indecent exposure and agreeing to secure a prostitute. He is held on bond of $1,250.

Areis faces charges of exposure of sexual organs and soliciting lewdness. He is held on bond of $1,500.

Green faces charges of exposure of sexual organs and soliciting prostitution. He is held on bond of $1,500.

News 6 has reached out to UCF for a statement and is awaiting a response.
